Market Trends & Challenges

The Mobile Network in 2011 and 2012

� Last year’s mobile data traffic was eight times the size of the entire global Internet in 2000.

� Mobile video traffic will exceed 50 percent for the first time in 2011

� Smartphones represent only 12 percent of total global handsets in use today, but they represent over 82 percent of total global handset traffic.

The Mobile Network in 2016

� Global mobile data traffic will increase 18-fold between 2011 and 2016

� Two-thirds of the world’s mobile data traffic will be video by 2016

� Mobile-connected tablets will generate almost as much traffic in 2016 as the entire global mobile network in 2012

Security Devices in LTE

� LTE or Mobile networks are full of security devices


Top 10 Testing Tips for Security Devices

1. Application Mix

� It’s important to tune the devices appropriately for the application running within the environment

� A simple mix of HTTP,SMTP,DNS,FTP may not be a good representative of your network

� The device under test should also be configured to protect all the applications.

2. Packet Size Mix

� A “normal” RFC 2544 is not recommended

� Instead of using single Packet sizes use a MIX different Sizes

� To understand the traffic mix administrators can use a protocol analyser to collect statistics form the real-life environment



3. Security Coverage

� It’s important to tune the devices appropriately for the application running within the environment

� Don’t use the “Standard” preconfigured filters, signatures and rules

4. VLAN Tagging

� VLAN Tag will consume processing resources within the security device

5. IPv6

� Use IPv4 and IPv6 simultaneously

6. Attacks Traffic

� Mix of both legitimate and malicious traffic

7. TCP sessions

� Ensure that performance test are conducted with a appropriate amount of TCP Sessions



8. Physical Connectivity

� Test Setup must reflect the real-life physical environment

� For modular designed devices it will be important to test traffic going into one module and out of a different module

9. Performance Testing for Long-Haul

� Take into account that the device will likely need to support growth over his lifetime.

� Global IP traffic is expected to increase fourfold over the next five years.

10.The Point of Failure

� One of the final tests is to find the point at which the device essentially fails.

It’s all about apps


What is there to test?

� Applications suffer from low bandwidth

• Response time goes low

• Retransmissions saturate the network

� Applications are not always designed for Mobile

� Application are still very similar to fixed Internet

• Browsing

• Skype

• Email

� Infrastructure testing with multiple applications is a must


Testing these applications

� This is very similar to testing applications in the web. Hence the web is providing the services.

� The extra comes with the mobile bandwidth that can be reached with multiple emulated users.

• Bandwidth has impact on performance of the application

• How many mobile users a can you handle

Most of the traffic is to be Video…


How does that work

For ABR to work, a video is first encoded at different bitrates to accommodate varying bandwidth connections. Each bitrate version is sliced up into tiny fragments —typically 2 to 10 seconds.

The video player then pulls fragments from the different encodings and inserts them into the stream as bandwidth dictates.


Adaptive Bitrate Streaming –The 4 C’s of Streaming TV

Consumption - Adapting to bandwidth, network conditions, and client CPU usage to deliver uninterrupted video

Connections - Client responsibility to request appropriate bit rate(s)

Continuity - Minimize delay by using WAN

acceleration technologies (caching

appliances)

Content - Cache video content on the edge and

distribute based on client requests
